9. USING THE INTERCOM

9.1 INTRODUCTION The G4 provides you with an impressive Bike-to-Bike Intercom range by simply flipping up the antenna. The Flip-up antenna allows you to maximize intercom range with Flip-up Antenna other bikers at up to 1mile / 1.6 km for extended range (subject to terrain). The antenna is also useful when riding in dense urban environments that may affect the transmission quality. You may keep the Flip-up Antenna open when not using the intercom, even though there is no particular need to do so. To set up one or two Intercom Bluetooth connections, you must first pair your G4 with the other devices. In this manual such other devices will be referred to as CHANNEL A and CHANNEL B respectively. Pairing is a one-time process. Once completed, the G4s will remain paired and automatically recognize each other whenever they are within range. For details on Intercom use with other scala rider units, please refer to section 9.11 below The G4 has two Intercom channels available for multiple intercom connections. Therefore, your G4 can communicate simultaneously with up to two other G4s. If one of these other G4s is connected to yet another G4, then all four participants can enter into a 4-way conference mode (see section 9.10c below).
9.2 BACKWARDS COMPATIBILITY The G4 can also conduct Intercom communications with earlier scalarider models in different configurations and you can always change your preferences. There are other scalarider models available that your G4 can connect to, and each of these connections comes with specific characteristics and / or limitations. In terms of range, Intercom communications between your G4 and another scala rider unit is limited to the distance of the lesser-range device. For example, connecting your G4 with a Q2 pro unit will enable intercom distances of up to 2,300 ft / 700 m, which is the maximum rated distance the Q2 pro can achieve. In the section below you can find out how to pair your G4 with other scalarider models. In addition, the G4 is also fully compatible with the Schuberth SRC-System. For details, visit www.cardosystems.com/src. 9.3 BEFORE STARTING THE INTERCOM The G4 has two buttons designated for quick connection to two other units. These other units are referred to as CHANNEL A and CHANNEL B. In the following sections you will also learn how to add a third participant and conduct an intercom conference.

9.6 VOICE CONNECT FEATURE (VOX) The G4 offers VOX technology for safe and hands-free operation of some key functions. For incoming calls, just pronounce loudly any word (e.g. hello). To reject an incoming call, remain silent for about 15 seconds. To reject an Intercom call remain silent for 30 seconds.
NOTE: The Enable/Disable Voice Connect feature affects only the Intercom functionality.
ENABLE/DISABLE VOX can be done via the PC software and directly on your G4 via the Settings Customization Voice Menu (see section 4.2). 9.7 RESET PAIRING (RESTORING THE ORIGINAL DEFAULT CONFIGURATION) This section is only relevant once you have completed a pairing process You can delete all of your paired devices at any time as follows: 1. With the G4 turned ON, press and hold the Mobile Button for at least six seconds until the Red and Blue Lights begin rapidly alternating. 2. Press and hold the Volume Up Button for three seconds. 3. The Red and Blue Lights will flash five times simultaneously and then the G4 will turn off, confirming that Reset was successfully completed. 9.8 NOTEWORTHY ISSUES a. Connecting the G4 to other units To pair your G4 to other scala rider models, please refer to section 9.10 c below. b. Busy Status (When using a G4) When attempting an Intercom call with a device that is already on a Phone/GPS/Intercom call, you will hear two beeps indicating the other device is busy.
